As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1 , negative charge will build up on the bottom plate while positive charge builds up on the top plate.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
The higher the value of capacitance, the more charge the capacitor can store. The larger the area of the plates or the smaller their separation the more charge the capacitor can store. A capacitor is said to be “Fully Charged” when the voltage across its plates equals the supply voltage.
When an electric current flows into the capacitor, it charges up, so the electrostatic field becomes much stronger as it stores more energy between the plates.
When used in a direct current or DC circuit, a capacitor charges up to its supply voltage but blocks the flow of current through it because the dielectric of a capacitor is non-conductive and basically an insulator.
Parallel connected capacitors have a common supply voltage across them. Series connected capacitors have a common current flowing through them. Capacitive reactance, X C is the opposition to current flow in AC circuits. In AC capacitive circuits the voltage “lags” the current by 90 o.
